“Reason is natural Revelation, whereby the eternal Father of Light and Fountain of all Knowledge communicates to mankind that portion of truth which he has laid within the reach of their natural faculties. Revelation is natural Reason enlarged by a new set of discoveries, communicated by God immediately, which Reason vouches the truth of, by the testimony and proofs it gives that they come from God. So that he that takes away Reason to make way for Revelation puts out the light of both, and does much what the same as if he would persuade a man to put out his eyes the better to receive the remote light of an invisible star by a telescope.”—Locke, Essay, Book IV. Chap. xix. § 4.
